DJI Spark vs. Zerotech Dobby

DJI Spark vs Zerotech Dobby

Unveiled in May 2017, the DJI Spark was the smallest drone offered by DJI when it debuted. Since then the company began selling the Dobby drone, from Zerotech, an aircraft which brings new meaning to the term diminuitive. The Zerotech Dobby provides consumers with an even cheaper drone model, priced at just $349 (compared to $499 for the Spark). This dip in price brings some unique advantages and disadvantages for the Zerotech Dobby compared to the Spark. Join us as we compare and contrast these two ultra small, ultra lightweight drones:


Speed and Performance


Zerotech Dobby in Flight

Although there are many interesting differences between these two drones, their overall performance is a key distinguishing point. Speed and overall flight time are two strong talking points for the DJI Spark, which manages a 31 mph top speed and 16 minutes of flight on a single charge. The Dobby is slightly disappointing, producing a meager 9 minutes of flight time and a top speed of 16 mph. That top speed comes at a cost, however, as the Dobby drone does not have the 2-axis gimbal of the Spark, affecting the overall quality of the photos and videos. 


Transmission Distance

DJI Spark

This category illustrates how alike these two drones are. When flying without the dedicated controller, the transmission distance of the DJI Spark is identical to its Zerotech counterpart, capable of 100 meters (109 yards). Spark pilots can expect a generous boost when using the dedicated controller, however, with 1.2 miles of range. Ultimately, flying with the Spark controller allows for a substantial range boost, but the two drones are neck and neck when flying with a mobile device. 



Size and Weight

Dobby:  1.4(H) x 5.3(W) x 5.7(L) inches 

Spark:   2.1(H) x 5.6(W) x 5.6(L) inches

These two diminutive drones are very similar in size and weight: the Dobby is smaller both when folded and unfolded. The DJI Spark has fixed arms, making it slightly harder to transport. The compact size of the Dobby means you don't even need a carrying case! Simply stash it in your pocket or purse, and unfold it to be ready for takeoff. 

Although the difference in size is slight, their different weights vary by an even closer margin. The DJI Spark is just slightly heavier than the Dobby.


Dobby: 199g (0.43 pounds)

Spark: 300g (0.66 pounds)



There are more than a few differences between the Spark camera and the camera onboard the Zerotech Dobby. For starters, the Dobby's camera does not have the image stabilization of its counterpart because it utilizes no gimbal. The two-axis gimbal of the Spark gives it a noted advantage. On the other hand, the Dobby boasts better overall image quality, capable of shooting 4K video and capturing 13 MP pictures. (These figures should be taken with a grain of salt, of course, because the lack of a gimbal can affect the quality of the photos and videos taken by the Dobby drone). By comparison, the Spark can shoot 1080p videos and capture 12 MP photos. 

Another interesting difference between the two is the use of Gesture Controls for the DJI Spark. When flying without a dedicated controller or a mobile device, Spark pilots can snap pictures with a hand gesture, a fun trick that shows promise and may be a standard feature in drones to come.
